fp@1732: GNU GENERAL PUBLIC LICENSE fp@1732: Version 2, June 1991 fp@1732: fp@1732: Copyright (C) 1989, 1991 Free Software Foundation, Inc. fp@1732: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@1732: Everyone is permitted to copy and distribute verbatim copies fp@1732: of this license document, but changing it is not allowed. fp@1732: fp@1732: Preamble fp@1732: fp@1732: The licenses for most software are designed to take away your fp@1732: freedom to share and change it. By contrast, the GNU General Public fp@1732: License is intended to guarantee your freedom to share and change free fp@1732: software--to make sure the software is free for all its users. This fp@1732: General Public License applies to most of the Free Software fp@1732: Foundation's software and to any other program whose authors commit to fp@1732: using it. (Some other Free Software Foundation software is covered by fp@1732: the GNU Library General Public License instead.) You can apply it to fp@1732: your programs, too. fp@1732: fp@1732: When we speak of free software, we are referring to freedom, not fp@1732: price. Our General Public Licenses are designed to make sure that you fp@1732: have the freedom to distribute copies of free software (and charge for fp@1732: this service if you wish), that you receive source code or can get it fp@1732: if you want it, that you can change the software or use pieces of it fp@1732: in new free programs; and that you know you can do these things. fp@1732: fp@1732: To protect your rights, we need to make restrictions that forbid fp@1732: anyone to deny you these rights or to ask you to surrender the rights. fp@1732: These restrictions translate to certain responsibilities for you if you fp@1732: distribute copies of the software, or if you modify it. fp@1732: fp@1732: For example, if you distribute copies of such a program, whether fp@1732: gratis or for a fee, you must give the recipients all the rights that fp@1732: you have. You must make sure that they, too, receive or can get the fp@1732: source code. And you must show them these terms so they know their fp@1732: rights. fp@1732: fp@1732: We protect your rights with two steps: (1) copyright the software, and fp@1732: (2) offer you this license which gives you legal permission to copy, fp@1732: distribute and/or modify the software. fp@1732: fp@1732: Also, for each author's protection and ours, we want to make certain fp@1732: that everyone understands that there is no warranty for this free fp@1732: software. If the software is modified by someone else and passed on, we fp@1732: want its recipients to know that what they have is not the original, so fp@1732: that any problems introduced by others will not reflect on the original fp@1732: authors' reputations. fp@1732: fp@1732: Finally, any free program is threatened constantly by software fp@1732: patents. We wish to avoid the danger that redistributors of a free fp@1732: program will individually obtain patent licenses, in effect making the fp@1732: program proprietary. To prevent this, we have made it clear that any fp@1732: patent must be licensed for everyone's free use or not licensed at all. fp@1732: fp@1732: The precise terms and conditions for copying, distribution and fp@1732: modification follow. fp@1732: fp@1732: GNU GENERAL PUBLIC LICENSE fp@1732: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION fp@1732: fp@1732: 0. This License applies to any program or other work which contains fp@1732: a notice placed by the copyright holder saying it may be distributed fp@1732: under the terms of this General Public License. The "Program", below, fp@1732: refers to any such program or work, and a "work based on the Program" fp@1732: means either the Program or any derivative work under copyright law: fp@1732: that is to say, a work containing the Program or a portion of it, fp@1732: either verbatim or with modifications and/or translated into another fp@1732: language. (Hereinafter, translation is included without limitation in fp@1732: the term "modification".) Each licensee is addressed as "you". fp@1732: fp@1732: Activities other than copying, distribution and modification are not fp@1732: covered by this License; they are outside its scope. The act of fp@1732: running the Program is not restricted, and the output from the Program fp@1732: is covered only if its contents constitute a work based on the fp@1732: Program (independent of having been made by running the Program). fp@1732: Whether that is true depends on what the Program does. fp@1732: fp@1732: 1. You may copy and distribute verbatim copies of the Program's fp@1732: source code as you receive it, in any medium, provided that you fp@1732: conspicuously and appropriately publish on each copy an appropriate fp@1732: copyright notice and disclaimer of warranty; keep intact all the fp@1732: notices that refer to this License and to the absence of any warranty; fp@1732: and give any other recipients of the Program a copy of this License fp@1732: along with the Program. fp@1732: fp@1732: You may charge a fee for the physical act of transferring a copy, and fp@1732: you may at your option offer warranty protection in exchange for a fee. fp@1732: fp@1732: 2. You may modify your copy or copies of the Program or any portion fp@1732: of it, thus forming a work based on the Program, and copy and fp@1732: distribute such modifications or work under the terms of Section 1 fp@1732: above, provided that you also meet all of these conditions: fp@1732: fp@1732: a) You must cause the modified files to carry prominent notices fp@1732: stating that you changed the files and the date of any change. fp@1732: fp@1732: b) You must cause any work that you distribute or publish, that in fp@1732: whole or in part contains or is derived from the Program or any fp@1732: part thereof, to be licensed as a whole at no charge to all third fp@1732: parties under the terms of this License. fp@1732: fp@1732: c) If the modified program normally reads commands interactively fp@1732: when run, you must cause it, when started running for such fp@1732: interactive use in the most ordinary way, to print or display an fp@1732: announcement including an appropriate copyright notice and a fp@1732: notice that there is no warranty (or else, saying that you provide fp@1732: a warranty) and that users may redistribute the program under fp@1732: these conditions, and telling the user how to view a copy of this fp@1732: License. (Exception: if the Program itself is interactive but fp@1732: does not normally print such an announcement, your work based on fp@1732: the Program is not required to print an announcement.) fp@1732: fp@1732: These requirements apply to the modified work as a whole. If fp@1732: identifiable sections of that work are not derived from the Program, fp@1732: and can be reasonably considered independent and separate works in fp@1732: themselves, then this License, and its terms, do not apply to those fp@1732: sections when you distribute them as separate works. But when you fp@1732: distribute the same sections as part of a whole which is a work based fp@1732: on the Program, the distribution of the whole must be on the terms of fp@1732: this License, whose permissions for other licensees extend to the fp@1732: entire whole, and thus to each and every part regardless of who wrote it. fp@1732: fp@1732: Thus, it is not the intent of this section to claim rights or contest fp@1732: your rights to work written entirely by you; rather, the intent is to fp@1732: exercise the right to control the distribution of derivative or fp@1732: collective works based on the Program. fp@1732: fp@1732: In addition, mere aggregation of another work not based on the Program fp@1732: with the Program (or with a work based on the Program) on a volume of fp@1732: a storage or distribution medium does not bring the other work under fp@1732: the scope of this License. fp@1732: fp@1732: 3. You may copy and distribute the Program (or a work based on it, fp@1732: under Section 2) in object code or executable form under the terms of fp@1732: Sections 1 and 2 above provided that you also do one of the following: fp@1732: fp@1732: a) Accompany it with the complete corresponding machine-readable fp@1732: source code, which must be distributed under the terms of Sections fp@1732: 1 and 2 above on a medium customarily used for software interchange; or, fp@1732: fp@1732: b) Accompany it with a written offer, valid for at least three fp@1732: years, to give any third party, for a charge no more than your fp@1732: cost of physically performing source distribution, a complete fp@1732: machine-readable copy of the corresponding source code, to be fp@1732: distributed under the terms of Sections 1 and 2 above on a medium fp@1732: customarily used for software interchange; or, fp@1732: fp@1732: c) Accompany it with the information you received as to the offer fp@1732: to distribute corresponding source code. (This alternative is fp@1732: allowed only for noncommercial distribution and only if you fp@1732: received the program in object code or executable form with such fp@1732: an offer, in accord with Subsection b above.) fp@1732: fp@1732: The source code for a work means the preferred form of the work for fp@1732: making modifications to it. For an executable work, complete source fp@1732: code means all the source code for all modules it contains, plus any fp@1732: associated interface definition files, plus the scripts used to fp@1732: control compilation and installation of the executable. However, as a fp@1732: special exception, the source code distributed need not include fp@1732: anything that is normally distributed (in either source or binary fp@1732: form) with the major components (compiler, kernel, and so on) of the fp@1732: operating system on which the executable runs, unless that component fp@1732: itself accompanies the executable. fp@1732: fp@1732: If distribution of executable or object code is made by offering fp@1732: access to copy from a designated place, then offering equivalent fp@1732: access to copy the source code from the same place counts as fp@1732: distribution of the source code, even though third parties are not fp@1732: compelled to copy the source along with the object code. fp@1732: fp@1732: 4. You may not copy, modify, sublicense, or distribute the Program fp@1732: except as expressly provided under this License. Any attempt fp@1732: otherwise to copy, modify, sublicense or distribute the Program is fp@1732: void, and will automatically terminate your rights under this License. fp@1732: However, parties who have received copies, or rights, from you under fp@1732: this License will not have their licenses terminated so long as such fp@1732: parties remain in full compliance. fp@1732: fp@1732: 5. You are not required to accept this License, since you have not fp@1732: signed it. However, nothing else grants you permission to modify or fp@1732: distribute the Program or its derivative works. These actions are fp@1732: prohibited by law if you do not accept this License. Therefore, by fp@1732: modifying or distributing the Program (or any work based on the fp@1732: Program), you indicate your acceptance of this License to do so, and fp@1732: all its terms and conditions for copying, distributing or modifying fp@1732: the Program or works based on it. fp@1732: fp@1732: 6. Each time you redistribute the Program (or any work based on the fp@1732: Program), the recipient automatically receives a license from the fp@1732: original licensor to copy, distribute or modify the Program subject to fp@1732: these terms and conditions. You may not impose any further fp@1732: restrictions on the recipients' exercise of the rights granted herein. fp@1732: You are not responsible for enforcing compliance by third parties to fp@1732: this License. fp@1732: fp@1732: 7. If, as a consequence of a court judgment or allegation of patent fp@1732: infringement or for any other reason (not limited to patent issues), fp@1732: conditions are imposed on you (whether by court order, agreement or fp@1732: otherwise) that contradict the conditions of this License, they do not fp@1732: excuse you from the conditions of this License. If you cannot fp@1732: distribute so as to satisfy simultaneously your obligations under this fp@1732: License and any other pertinent obligations, then as a consequence you fp@1732: may not distribute the Program at all. For example, if a patent fp@1732: license would not permit royalty-free redistribution of the Program by fp@1732: all those who receive copies directly or indirectly through you, then fp@1732: the only way you could satisfy both it and this License would be to fp@1732: refrain entirely from distribution of the Program. fp@1732: fp@1732: If any portion of this section is held invalid or unenforceable under fp@1732: any particular circumstance, the balance of the section is intended to fp@1732: apply and the section as a whole is intended to apply in other fp@1732: circumstances. fp@1732: fp@1732: It is not the purpose of this section to induce you to infringe any fp@1732: patents or other property right claims or to contest validity of any fp@1732: such claims; this section has the sole purpose of protecting the fp@1732: integrity of the free software distribution system, which is fp@1732: implemented by public license practices. Many people have made fp@1732: generous contributions to the wide range of software distributed fp@1732: through that system in reliance on consistent application of that fp@1732: system; it is up to the author/donor to decide if he or she is willing fp@1732: to distribute software through any other system and a licensee cannot fp@1732: impose that choice. fp@1732: fp@1732: This section is intended to make thoroughly clear what is believed to fp@1732: be a consequence of the rest of this License. fp@1732: fp@1732: 8. If the distribution and/or use of the Program is restricted in fp@1732: certain countries either by patents or by copyrighted interfaces, the fp@1732: original copyright holder who places the Program under this License fp@1732: may add an explicit geographical distribution limitation excluding fp@1732: those countries, so that distribution is permitted only in or among fp@1732: countries not thus excluded. In such case, this License incorporates fp@1732: the limitation as if written in the body of this License. fp@1732: fp@1732: 9. The Free Software Foundation may publish revised and/or new versions fp@1732: of the General Public License from time to time. Such new versions will fp@1732: be similar in spirit to the present version, but may differ in detail to fp@1732: address new problems or concerns. fp@1732: fp@1732: Each version is given a distinguishing version number. If the Program fp@1732: specifies a version number of this License which applies to it and "any fp@1732: later version", you have the option of following the terms and conditions fp@1732: either of that version or of any later version published by the Free fp@1732: Software Foundation. If the Program does not specify a version number of fp@1732: this License, you may choose any version ever published by the Free Software fp@1732: Foundation. fp@1732: fp@1732: 10. If you wish to incorporate parts of the Program into other free fp@1732: programs whose distribution conditions are different, write to the author fp@1732: to ask for permission. For software which is copyrighted by the Free fp@1732: Software Foundation, write to the Free Software Foundation; we sometimes fp@1732: make exceptions for this. Our decision will be guided by the two goals fp@1732: of preserving the free status of all derivatives of our free software and fp@1732: of promoting the sharing and reuse of software generally. fp@1732: fp@1732: NO WARRANTY fp@1732: fp@1732: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY fp@1732: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN fp@1732: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES fp@1732: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED fp@1732: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF fp@1732: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS fp@1732: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE fp@1732: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, fp@1732: REPAIR OR CORRECTION. fp@1732: fp@1732: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING fp@1732: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR fp@1732: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, fp@1732: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING fp@1732: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED fp@1732: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY fp@1732: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER fp@1732: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE fp@1732: POSSIBILITY OF SUCH DAMAGES. fp@1732: fp@1732: END OF TERMS AND CONDITIONS fp@1732: fp@1732: How to Apply These Terms to Your New Programs fp@1732: fp@1732: If you develop a new program, and you want it to be of the greatest fp@1732: possible use to the public, the best way to achieve this is to make it fp@1732: free software which everyone can redistribute and change under these terms. fp@1732: fp@1732: To do so, attach the following notices to the program. It is safest fp@1732: to attach them to the start of each source file to most effectively fp@1732: convey the exclusion of warranty; and each file should have at least fp@1732: the "copyright" line and a pointer to where the full notice is found. fp@1732: fp@1732: fp@1732: Copyright (C) fp@1732: fp@1732: This program is free software; you can redistribute it and/or modify fp@1732: it under the terms of the GNU General Public License as published by fp@1732: the Free Software Foundation; either version 2 of the License, or fp@1732: (at your option) any later version. fp@1732: fp@1732: This program is distributed in the hope that it will be useful, fp@1732: but WITHOUT ANY WARRANTY; without even the implied warranty of fp@1732: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the fp@1732: GNU General Public License for more details. fp@1732: fp@1732: You should have received a copy of the GNU General Public License fp@1732: along with this program; if not, write to the Free Software fp@1732: Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA fp@1732: fp@1732: fp@1732: Also add information on how to contact you by electronic and paper mail. fp@1732: fp@1732: If the program is interactive, make it output a short notice like this fp@1732: when it starts in an interactive mode: fp@1732: fp@1732: Gnomovision version 69, Copyright (C) year name of author fp@1732: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. fp@1732: This is free software, and you are welcome to redistribute it fp@1732: under certain conditions; type `show c' for details. fp@1732: fp@1732: The hypothetical commands `show w' and `show c' should show the appropriate fp@1732: parts of the General Public License. Of course, the commands you use may fp@1732: be called something other than `show w' and `show c'; they could even be fp@1732: mouse-clicks or menu items--whatever suits your program. fp@1732: fp@1732: You should also get your employer (if you work as a programmer) or your fp@1732: school, if any, to sign a "copyright disclaimer" for the program, if fp@1732: necessary. Here is a sample; alter the names: fp@1732: fp@1732: Yoyodyne, Inc., hereby disclaims all copyright interest in the program fp@1732: `Gnomovision' (which makes passes at compilers) written by James Hacker. fp@1732: fp@1732: , 1 April 1989 fp@1732: Ty Coon, President of Vice fp@1732: fp@1732: This General Public License does not permit incorporating your program into fp@1732: proprietary programs. If your program is a subroutine library, you may fp@1732: consider it more useful to permit linking proprietary applications with the fp@1732: library. If this is what you want to do, use the GNU Library General fp@1732: Public License instead of this License.
